bro bro about u cannot reach the chords, "don't fret on the problem!" ok i don't mean it literally.
do some simple checks when u are doing ur chords.
1. Are You Using The Correct Fingers Stated In Ur Book/Video For That Chord?
(this could be the major problem that makes u go "wtf theres no way my first finger can reach that!"
2. For Some Chords, Only SOME, Make An Exception To Use Ur Preferred Fingering, Still Ensure That The Tone Is Right!
(for example, i always use my thrid finger on the first string when doing a G instead of my pinkie)
3. Make Sure No Fingers Are "accidently" Touching The Rest Of Tha Strings, Don't Just Think, Aiyah Mute Alittle Only Barhs, People Won't Differentciate.
4. Practice Makes Perfect, Do Not Rush To Learn Your Whole Chord Book In An Hour. For Me I Just Revise/Play Over And Again 3 - 5 Chords A Day And Slowly U Can Play Some Songbooks/Tabs.
5. Don't Scream When U Find U're Fingertips Getting Stiff, Flakey Or Hard. Those Are Callapses aka Hard Skin Which Makes Fretting Easier.
I know im not fit to teach anyone lol. just my 5cents donation =P
